2- Characteristics of the Species Durio dulcis Becc. - Red Durian or Lahong tree
2.1- Description
+ The plants
Durio dulcis is a fairly large tree that can grow up to 40 metres tall with bole up to 80 cm in diameter having large buttresses up to 4 m high, bark surface rough, superficially fissured or irregularly flaky, reddish-brown.
+ The leaves
Leaves are alternate, simple, penni-veined, silvery-golden below, very similar to those of Durio acutifolius, but veins looping more clearly and more conspicuous scales on lower surface.
Leaves elliptical or obovate-elliptical, 7-14 cm × 3.5-6 cm, densely scaly below.
+ The flowers
Flowers in short inflorescence clustered on older branches, petals up to 45 mm long, pink, stamens in bundles, opening by a slit.
Flowers are 33 mm in diameter, white-reddish, with 2-lobed epicalyx, placed in small clusters on the twigs behind the leaves.
+ The fruits
Fruit is up to 15 cm diameter, dark red to red-brown, with slender 15-20 mm long spines, very strong smelling. The flesh of the fruit is yellow, sweet, delicious and noted for its intense lingering taste. The fruit of this species is considered by many to be the sweetest of all durians.
The edible fruit is gathered from the wild and sold in local and urban markets, but the species is rarely planted because of its short fruiting period.
+ The seeds
Seeds are dark brown, size 2-3 cm, each completely covered by a dark yellow aril.
Seeds are a glossy dark brown and the indigenous people claim that the cooked (boiled or roasted) seeds are sexually rejuvenating!
